Administrative History

When the Department of State Police was first organized in 1917, each of the original four Troops, following military and modern police practices, began maintaining a record of their activities in blotter form. As new Troops were added to the force, they too began maintaining their own blotters. During the 1920s and 1930s many patrol or substations were established throughout the state. Although these units reported to Troop Headquarters, they maintained their own blotters. After 1935, each Troop had a Bureau of Criminal Investigation Unit attached to it. These units were semi-autonomous, reporting directly to the Troop's captain. Consequently, these units maintained their own files and blotters.
